I re-installed Indesign CS5.5 today on new PC - Windows 8 - (old PC crashed catastrophically and data cannot be retrieved) but cannot launch the programme. I get the message 'Please select a .folio file' and nothing else.
No chat or technical help available now for CS5.5, so the forum is my only hope. Any ideas/insights gratefully seized upon.
The only application that would produce that message is the Adobe Content Viewer, not InDesign.
Thanks Bob. Your response got me realising that a whole chunk of the download was missing. A restart has fixed the problem.
